Started seeing /forest/_internal/capabilities endpoint failures in our project logs

Help me!

Feature(s) impacted

Forest Admin project environment loaded in browser with failures observed in network for endpoint /forest/_internal/capabilities. Seems this endpoint is not implemented in our code repo and not sure if there is inbuilt implementation supported through forest package.

Observed behavior

Endpoint failures are being observed in project logs causing alerts being triggered. As our project is using forest-express-sequelize 9.6.10. If any custom implementation is required to support this new endpoint from project team ?

Expected behavior

App to launch all environments without any failures observed through forest admin

Hi,

Thanks for flagging this — you were right to.

We’ve confirmed it on our side. The fix is merged and will be live with our next release, after which those calls will stop appearing in your logs and alerts.

No action is needed on your end. Sorry for the noise, and thanks for the clear report.

Best,
